I still have all of my Nancy Drew books (my brother got the Happy Hollister collection) and said daughter has read almost all the Nancy's but recently pronounced she does not care for them very much, so I'm going to be selling the ones in decent condition on ebay.

I'm guessing that they're too "old-fashioned" for them. My son came close to reading a Hardy Boys book, but he gave up on it. Too many characters to keep track of. It was a school assignment and he got to pick the book that he wanted to read (within the genre of the month), so I figured that if wanted to start over with another book, that was probably the best decision for him. (He's in 3rd grade, so it might've been a little much for him anyway.)
